I remember I have read somewhere of the same problem, can not find that post anywhere, reason I am posting here to check against other 1DX camera owners, please reply if yes or no.

When looking through viewfinder, the focusing screen has a circle and inside it is the focusing confirmation square which in my case is off center to the left. Have replaced the focusing screens twice with different screens and the problem is consistent. If you have a Canon 1DX can you check please and reply how is your setup? Should I shake the camera to get the square to fall into place :), should live with it or call Canon and send it back? The camera was bought from B&H recently and wonder if I should return it.

Have made a rendition of the problem to help visualize the off center location.
